Running Applications in a Virtual Machine (VM)

This is a rough guide to installing the open source cloud application OpenStack in a virtual machine (VM) using DevStack. I have managed to get it deployed after dealing with a number of authentication issues. Next step after the deployment is getting the Horizon dashboard up and running. Stay tuned. OpenStack in a VM

For those who work with SDN/NFV and cloud technologies, a network emulator is a good way to keep sharp with the technology. Last time I spent a considerable amount of time out west, I bought a bunch of used network equipment from Weird Stuff Warehouse and built a rack with a SuperMicro Server, 96 port Ethernet switches, and 4 Cisco routers, an open source Vyatta router and 5 hosts and used it to practice for my Cisco certifications. I sold the setup when I returned to Dallas. One can do alot of the same type of network experimentation using the Mininet emulator. Here is a link to a tutorial that I created for this, the steps being as follows:

Download the Oracle open source hypervisor VirtualBox

Download the Mininet VM

Download Xming, which provides the tunnel from the VM to a terminal program running outside the VM

Download the terminal program PuTTY

Follow the steps below to configure the various components then set up a network and view with Wireshark
